The embodiments described below by reference to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

[0036] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting and the like should be broadly understood, and the skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0037] The driver monitoring system (DMS, Driver monitoring system) is a system for determining the driving state of the driver by collecting the driver's facial image, physiological index or vehicle information processing, realizing the functions of fatigue monitoring, distraction monitoring and dangerous driving behavior monitoring (such as drunk driving, holding a phone and drinking water, etc.) of the driver. In the environment with insufficient environmental light, a light supplement device is often used for light supplement to enhance the imaging effect of the camera.

[0038] However, the light supplement lamp in the light supplement device usually produces visible light frequency brightness sensitive to human eyes. On the one hand, in the environment with sufficient light, the driver is easy to directly observe the light supplement lamp and other components inside the light supplement assembly, affecting the appearance of the camera device; on the other hand, in the environment with insufficient light, the visible light emitted by the light supplement lamp is easy to interfere with the driver, affecting his normal driving.

[0039] To solve the above technical problems, some embodiments of the utility model provide a kind of vehicle-mounted camera 1000, it is applicable to vehicle, with reference to Figures 1 to 7 As shown in the description of vehicle-mounted camera 1000.

[0040] With reference to Figure 1 And Figure 2 As shown in the utility model embodiment, vehicle-mounted camera 1000 includes: mainboard 100, camera assembly 200 and light supplement component 300, wherein, in an example, mainboard 100 is printed circuit board (Printed Circuit Board, PCB), it can carry camera assembly 200, light supplement component 300 and other electronic components.In the embodiment, camera assembly 200 includes lens 210 and sensor 220, wherein, lens 210 one end is detachably connected with mainboard 100, and the other end is set into light hole.Sensor 220 is located between lens 210 and mainboard 100, and is connected with mainboard 100.It needs to be explained that lens 210 is used to capture light, and guide light to sensor 220, and sensor 220 is photosensitive element, which can convert optical image into electronic signal.

[0041] With reference to Figure 1 And Figure 2 As shown in the utility model embodiment, light supplement component 300 is arranged at the same side of mainboard 100 with camera assembly 200, specifically, light supplement component 300 and camera assembly 200 are installed at the front end of mainboard 100.In the embodiment, light supplement component 300 includes light emitting piece 310 and optical filter 320, along the arrangement direction of sensor 220 and lens 210, light emitting piece 310 and optical filter 320 are sequentially arranged.It needs to be explained that sensor 220 and lens 210 are sequentially arranged from right back to front.Light emitting piece 310 is connected to mainboard 100, which can be infrared light emitting diode, for emitting infrared light towards front side.Optical filter 320 is connected with mainboard 100, which can be erected at the front side of mainboard 100, so that light emitting piece 310 can be shielded in front of light emitting piece 310, to filter the light emitted by light emitting piece 310.

[0042] With reference to Figure 4As shown, in the embodiment of the utility model, the end surface of the filter 320 facing the mainboard 100 is evaporated with a coating layer 321, and the end surface of the filter 320 facing away from the mainboard 100 is coated with an ink layer 322, and the filter 320 is used to filter the visible light in the light emitted by the light emitting part 310. It can be understood that the front end surface of the filter 320 is the end facing the target object, and the rear end surface is the end of the filter 320 facing the light emitting part 310, therefore, the front end surface of the filter 320 is provided with the ink layer 322, and the rear end surface is provided with the coating layer 321. Based on this, the light emitted by the light emitting part 310 passes through the coating layer 321 on the rear end surface of the filter 320, the filter 320 and the ink layer 322 on the front end surface of the filter 320 in turn, and finally reaches the driver.

[0043] It can be understood that in the embodiment, the coating layer 321 and the ink layer 322 can cooperate to filter the visible light in the light emitted by the light emitting part 310, so that the light irradiated on the driver is non-visible light, avoiding visual interference to the driver. Figure 5 It can be understood that when the light emitted by the light emitting part 310 passes through the coating layer 321, the spectral curve shows that the coating layer 321 can preliminarily depress the spectrum of the visible light band, that is, filter part of the visible light. Figure 6 It can be understood that when the light filtered by the coating layer 321 passes through the ink layer 322, the spectral curve shows that the ink layer 322 can further depress the spectrum of the visible light band, that is, filter the remaining part of the visible light, therefore, the light after passing through the ink layer 322 is only the light of infrared wavelength, that is, infrared ray.

[0044] The vehicle-mounted camera device 1000 of the embodiment of the utility model is provided with a light supplementing assembly 300 on one side of the camera assembly 200, wherein the light supplementing assembly 300 comprises a light emitting part 310 and a filter 320, and the light emitting part 310 and the filter 320 are arranged in sequence along the arrangement direction of the sensor 220 and the lens 210, based on this, the light emitted by the light emitting part 310 will pass through the filter 320, and the end surface of the filter 320 facing the mainboard 100 is evaporated with a coating layer 321, and the end surface of the filter 320 facing away from the mainboard 100 is coated with an ink layer 322, therefore the filter 320 can filter the visible light in the light emitted by the light emitting part 310, thereby effectively reducing the irradiation of the visible light to the driver, not only reducing the interference of the light supplementing assembly 300 to the driver's line of sight in the dim environment, improving the driving safety, but also avoiding the driver from seeing the internal structure of the light supplementing assembly 300 in the bright environment, thereby enhancing the aesthetic property of the vehicle-mounted camera device 1000.

[0045] Referring to Figure 2 and Figure 3As shown in the utility model embodiment, the light supplement assembly 300 comprises a support 330, the support 330 is a hollow structure of a cylinder, specifically, a light guide groove 331 is arranged inside the support 330, and the light guide groove 331 extends along the front-rear direction and penetrates through the support 330. One end of the support 330 is detachably connected with the main plate 100, and the other end is connected with the light filter 320. Based on this, the light filter 320 is installed at the front end of the support 330, and the light emitting piece 310 is located in the light guide groove 331. It can be understood that the light emitted by the light emitting piece 310 can be conducted in the light guide groove 331 and shot to the light filter 320, which ensures that the light emitted by the light emitting piece 310 must pass through the light filtering of the light filter 320 before being shot to the driver.

[0046] With reference to Figure 2 and Figure 3 As shown in the utility model embodiment, the inner wall of the light guide groove 331 is provided with a first step 332, and the first step 332 is arranged at one end of the support 330 away from the main plate 100. Specifically, the first step 332 is protrudedly formed on the inner wall of the light guide groove 331, and the first step 332 is an annular structure arranged along the circumference of the light guide groove 331, which is located at the front end of the support 330, and the circumferential edge of the light filter 320 abuts against the first step 332, thereby realizing the fixation of the light filter 320. In an example, the light filter 320 is bonded to the first step 332.

[0047] With reference to Figure 2 and Figure 3 As shown in the utility model embodiment, the inner wall of the light guide groove 331 is further provided with a second step 333, specifically, the second step 333 is protrudedly formed on the inner wall of the light guide groove 331, and the second step 333 is an annular structure arranged along the circumference of the light guide groove 331, which is located between the front end and the rear end of the support 330. In this embodiment, along the arrangement direction of the light emitting piece 310 and the light filter 320, the second step 333 and the first step 332 are sequentially and spacedly arranged, that is, the second step 333 is located at the rear side of the first step 332. It should be noted that the inner diameter of the second step 333 is smaller than the inner diameter of the first step 332. The light supplement assembly 300 further comprises a mounting plate 340, the light emitting piece 310 is mounted on the mounting plate 340, and the circumferential edge of the mounting plate 340 abuts against the second step 333, for example, the mounting plate 340 is bonded to the second step 333. In an example, the light emitting piece 310 can be provided with a plurality of light emitting pieces 310, and the plurality of light emitting pieces 310 are spacedly arranged at the front end of the mounting plate 340.

[0048] With reference to Figure 1 and Figure 3As shown, in the embodiment of the present application, two camera assemblies 200 are arranged on the two sides of the light supplement assembly 300. Specifically, along the length direction of the main board 100, the camera assembly 200 and the light supplement assembly 300 are staggered, i.e. the light supplement assembly 300 is located in the middle position of the two camera assemblies 200, so that the infrared light emitted by the driver can be reflected in any direction and at least one camera assembly 200 can capture it.

[0049] In the embodiment of the present application, the wavelength of the visible light filtered by the coating layer 321 and the ink layer 322 is less than 920nm (nanometer), i.e. the light filtered by the coating layer 321 and the ink layer 322 is infrared light with a wavelength greater than or equal to 920nm, i.e. infrared, which ensures the imaging quality of the camera assembly 200.

[0050] It can be understood that the flatness of the coating layer 321 is crucial to the performance of the optical element. Smaller flatness means smaller irregularity of the surface, which helps to reduce optical scattering and diffraction, thereby improving the transmittance and reflectance of the optical filter 320. Based on this, in the embodiment of the present application, the flatness of the coating layer 321 is a, which satisfies: a < 30μm (micrometer), so that the coating layer 321 has the required optical performance and durability.

[0051] It can be understood that the inventors have learned in the test process that if the thickness of the ink layer 322 is too large, the transmittance of the ink layer 322 will be greatly reduced, making it difficult for the lens 210 to obtain sufficient light and reducing the imaging quality of the camera assembly 200; on the contrary, if the thickness of the ink layer 322 is too small, the light filtering performance of the ink layer 322 will be greatly reduced, so that the optical filter 320 cannot effectively filter out visible light and cannot meet the light filtering requirements of specific wavelengths. Based on this, in the embodiment of the present application, the thickness of the ink layer 322 is b, which satisfies: 5nm ≤ b ≤ 10nm, so that the optical filter 320 has the required transmittance while ensuring the light filtering performance of the optical filter 320. In one preferred embodiment, the thickness of the ink layer 322 is 8nm.

[0052] In the embodiment of the utility model, the filter 320 is a glass layer, specifically, the filter 320 can be a glass substrate, for example, blue glass, thereby reducing the risk of the filter 320 interfering with the passage of light, and reducing the manufacturing cost of the filter 320. In the embodiment of the utility model, the ink layer 322 includes infrared ink, a diluent, an additive, and a curing agent. It can be understood that the ink layer 322 often affects the curing effect due to insufficient drying after being applied to the filter 320, causing the ink layer 322 to easily fall off the filter 320. Based on this, in the embodiment of the utility model, the ink layer 322 is cured and pasted to the filter 320 by baking, ensuring that the ink layer 322 can be pasted to the filter 320, reducing the risk of the ink layer 322 falling off, and improving the durability and reliability of the filter 320.

[0053] The embodiment of the utility model also proposes a vehicle including the vehicle-mounted camera device 1000 of the above-mentioned embodiment. Specifically, the vehicle can be a private car, such as a sedan, an SUV, an MPV, or a pickup truck, etc. The vehicle can also be an operating vehicle, such as a van, a bus, a small truck, or a large trailer, etc. The vehicle can be a gasoline car or a new energy car. When the vehicle is a new energy car, it can be a hybrid car or a pure electric car.

[0054] The vehicle of the embodiment of the utility model adopts the vehicle-mounted camera device 1000 of the above-mentioned embodiment, which optimizes the structure of the vehicle-mounted camera device 1000, not only reducing the interference of the light supplement assembly 300 with the driver's line of sight in a dim environment, but also avoiding the driver from seeing the internal structure of the light supplement assembly 300 in a bright environment, thereby enhancing the aesthetics of the vehicle-mounted camera device 1000, on the one hand, improving the driving safety of the vehicle and reducing the risk of accidents, on the other hand, increasing the practicality and reliability of the vehicle-mounted camera device 1000, which helps to improve the performance of the driver monitoring system of the vehicle.

[0055] Since the vehicle adopts all the technical solutions of the vehicle-mounted camera device 1000 of the above-mentioned embodiment, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be repeated here.
